I loved playing this and I love the characters too. Thanks so much for translating it. :D
Spoilers?
I tried playing the minigame in the bonus room. The first time I used the perfume and got the "Squabble" ending. The second time I didn't use it but Seryozha said Hariton stunk like perfume again...I didn't even go in the bathroom! Then I got the same ending. So I think that might be a bug. I stopped trying to play it after that.
Thanks a lot for playing, I'm glad you enjoyed it!
Oh man, I'd thought I'd managed to patch out that sort of thing. There wasn't appropriate flagging in the original to make the minigame's event reset after playing, so I had added those in myself, but it seems something slipped through. I'm very sorry, but thank you for reporting this I'll try to fix it ASAP!
